Boise, ID – Emergency officials across Idaho are urging residents to begin preparing today for potential ice storms this winter, noting that freezing rain can create far more dangerous conditions than snowfall in many of the state’s valleys. According to the National Weather Service (NWS), temperature inversions and warm-front transitions can produce ice accumulation capable of snapping tree limbs and making major roadways hazardous across Southern and Western Idaho.
According to NOAA, even light ice buildup can overload weakened branches and threaten powerlines—particularly in the Treasure Valley, Magic Valley, and portions of North Idaho where cold air often becomes trapped near the surface. Ice can create extremely dangerous travel conditions along I-84, I-184, Highway 55, and rural connectors across Ada, Canyon, Elmore, and Twin Falls counties. With fluctuating temperatures expected this season, officials say today is the ideal time to take preventive winter steps.
According to the National Weather Service, residents should begin by trimming weak or damaged tree limbs around homes, garages, and sidewalks. These branches often fall first when ice begins to accumulate. NOAA also reminds drivers not to lift windshield wipers before storms, as they can freeze to the glass and snap; keeping them lowered and covered is recommended.
Families are encouraged to store at least a week’s supply of non-perishable food, bottled water, and essential prescriptions. Ice storms can trigger prolonged outages and make road conditions treacherous across valley communities and rural farmland. Officials further advise residents not to park vehicles beneath trees, where ice-laden branches may fall unexpectedly.
To prepare for potential outages, emergency managers recommend fully charging phones, flashlights, power banks, and essential electronics today. Homeowners who own generators should safely store extra gasoline and conduct a test run ahead of winter weather. Stocking rock salt or ice melt can also help reduce slip hazards around porches, walkways, and driveways.
“Even occasional ice storms can disrupt daily life across Idaho,” the NWS said. “Preparing today is the best way to stay safe this winter.”
